I was long-boarding, going about 12-14 mph when i hit a wall, I was not wearing a helmet so i tucked my head into my chest and curled my elbow into my ribcage. When i hit i was in shock, i could not breathe but i could move my arm . In the days after i lost most of the movement from my elbow, and it would always be a dull pain and when i tried to move it a sharp pain came from what seemed like inside my elbow. now almost 3 weeks after the incident i cannot fully curl my elbow up and i cannot fully extend my elbow and it is hard for me to twist it as if turning a doorknob. What do you think is wrong with my elbow? What can i do other than going to a physician can i do to fix it? I join the army in less than 2 weeks and i have to be in top physical condition, please help.
